Title: Method for measuring compositon of liquid containing fluoric acid and fluoride for steel plate pickling bath
Inventor: KAMIYO TAKAYOSHI
IPC: G01N31/16
Filed: 1983-02-22
Abstract: PURPOSE:To measure the composition of a pickling liquid for stainless steel at a high accuracy for a short period of time by performing a neutralizing titration of a sample liquid with an alkali solution using a pH meter after a calcium salt is added thereto. CONSTITUTION:After a calcium salt is added to a sample liquid, a neutraizing titration is done with an alkali solution using a pH meter to estimate the concentration of isolated acid from the first equivalence point and that of a melted metal from the second equivalence point. The calcium salt herein used are, for example, calcium chloride, calcium nitrate and calcium sulfate. The addition of the calcium salt enables the measurement of pH. A standard solution such as N3OH, KOH and LiOH may be used for the alkali solution for the alkali titration. Isolated acid and melted metal in a pickling liquid reacts upon alkali as exampled by the formulas (1)-(3) respectively. Therefore, the curve of this neutralizing titration presents the first equivalence point corresponding to the formula (1) and the second equivalence point corresponding to the formulas (2) and (3). Thus the concentration of isolated acid and that of melted metal can be determined.

Title: Superfinishing tool
Inventor: KOSONE TAKASHI
IPC: B24B33/04
Filed: 1985-02-16
Abstract: PURPOSE:To reduce the turning moment of a grindtone due to frictional force and to make a charactering vibration eliminative, by setting up the grindstone at the leading side as being offset, in case of superfinishing for crankshaft or the like. CONSTITUTION:When grindstones 7 being slidably attached to three spots on a peripheral surface of a tool head 1 via slide bars 8 are pressed to a work W in rotation for grinding, frictional force F works thereon. Here, each grindstone is offset to the leading side so that a retractable axis X of the grindstone 7 is obliquely crossed with a transverse line of action of the frictional force F, whereby turning moment M made by diretional component force Fa orthogonal with the axis X of the frictional force F comes smaller, thus a chattering vibration is hard to occur. If this leading angle theta is made larger, bending moment grows large with pressure reaction force acting on each grindstone 7, it should be set to a range of 10 deg.-30 deg. or so. Thus, the chattering vibration is hard to occur there and, what is more, durability is these grindstones and finishing accuracy in the work both are improved.

Abstract: PURPOSE:To reduce a connecting area between a substrate and buried diffusion layer by stacking an epitaxial layer on a Si substrate after selectively providing an insulating layer, further stacking a second epitaxial layer thereon in view of providing an active region within a single crystal Si layer and forming electrode connecting portion in contact with a lower single crystal layer. CONSTITUTION:A P<+> channel cut 21 and SiO2 buried layer 11 are provided on a P<-> type Si substrate 12, then a non-additive poly-Si is stacked thereon. Thus, a single crystal layer 22a and a polycrystalline layer 22b can be formed by laser annealing thereto. The As ion is selectively implanted, the surface is annealed followed by forming of an N<+> single crystal layer 14a and an N<+> polycrystalline layer 14b. Then, an N<+> layer 14 of the specified area defined by a SiO2 13 can be completed by selective thermal oxidation. Next, an N<-> type Si is epitaxially formed, then a single crystal layer 17a and a polycrystalline layer 17b are formed, and SiO2 15, 16 are then isolated by selective thermal oxidation. Thereafter, an N<+> connecting layer 18, P base, N<+> emitter 19 are provided by an ordinary method. Since the area where the buried layer 14 and substrate are directly in contact becomes about 1/2 of the conventional area, capacitance between isolated layers is reduced and operating speed can be improved.

Title: Hoist control method for crane provided with rope type bucket
Inventor: MANABE KEIJI
IPC: B66D1/62
Filed: 1988-02-09
Abstract: PURPOSE:To prevent abnormal opening of bucket by setting the output frequency of a supporting inverter such that the speed of both motors is identical based on a detected output frequency of an open/close inverter during hoist work. CONSTITUTION:An open/close motor M2 and a supporting motor M1 are started through a controller when hoist work is started, and when the rotation of the motor M2 reaches to N1, the current level increases to the limit level of an open/close inverter 12 thus stopping increase of the output frequency. Since a supporting rope R1 is loosened, the load torque of the motor M1 is low and the rotation starts to increase, but since the set frequency input corresponds to the rotation N1, increase of the frequency output stops. When the supporting rope R1 is not loosened and the load is balanced, the current of the motor M2 drops below the limit level of the inverter 12, and thereby acceleration is made upto the initial set frequency and both ropes R1, R2 are operated with arranged speed thus eliminating opening of a bucket 1.
